T 00% whom it may concern.- Beit known that I, WILLIAM FREDRIO COOPER, of Meriden, in the county of New Haven and State of- Connecticut, have invented a new and Improved Acetylene Lamp and Generator, of which the followin g is a full,

I clear, and exact description.

My invention relates to an improvementin H acetylene lamps or lanterns, and comprises 3 1c the novel features hereinafter described and claimed. I

Reference is to be had to the accompanying drawings, forming a part of this specification,

.; 3 y in which similar characters of reference indicate corresponding parts inall the views.

Figure l is a sectional elevation of my device. Fig. 2 is across-section taken upon the line 2 2 of Fig. 1. Fig. 3 is a detail seci tional elevation showing the valve and adjacent parts in a different position from that shown in Fig. 1. Fig. 4. is a perspective view showing the valve and its stem; and Fig. 5 is y a. detail sectional elevation through the dry ing-chamber, showing a burner attached.

The object of my invention is to provide a .p'ractical and simple lamp or lantern using acetylene gas for lighting, having more par- 1 ticularly in View the adaptation of the do vice for use upon bicycles. In my lamp or lantern the variation in volume of the gas-chamber is provided for by hav- .ing a portion of the wall thereof constructed of a flexible material and having the same I r. compressed by means of a spring. I At the base of the lamp or lantern is a chamber A, adapted to contain water and provided with a cap a, by means of which the contents may be renewed or discharged. At the upper end I of this chamberand at some distance above I H the level of the water is a conical flange 0, so-

cured at its outer edges to the Walls of the chamber and extending downwardly and to- H ward the center. I Theapex of this cone is removed,leav ing a passage connecting with the upper side of the flange. To therwalls of the chamber, at the upper edge of the flange O, is connected the expanding member D, which consists of leather, rubber, or. any suitable material which is 1 adapted to answer as the flexible wall ofa bellows. The upper edge of this bellows is connected with the lower portion of the chamber B, which is the carbid-holder. The bottom B of this chamber is of conical shape, corresponding substantially with the shape of the flange O. The opening at the apex of the cone forming the bottom B is smaller than that in the flange G. This opening is normally closed by a valve E, which is within the carbid-holder and seats over the opening. The valve E has a stem E extending downwardly, to the lower end of which is secured a pair of cross-arms E adapted to engage the upper surface of the conical flange G. The carbid L is placed within chamber B in powdered form, and will thus pass through the opening in the bottom and drop into the water when the valve E is raised. y

The valve E may be locked down, so that it may not be raised, by a rod G, which is threaded at its upper end and extends through a threaded hole in the top of the carbid-holder. This rod is provided with a knob G, by means of which it may be readily adjusted. A spiral spring 6 surrounds the stem of the valve, hearing at its lower end against the crossbars E and at its upper end against the bottom of the carbid-holder.

The spring 6 serves to hold the valve closed. A second spring F,

which is considerably stronger than the spring e, lies between'the upper surface of the conthe flexible connection D between the base of the lamp and the carbid-holder is compressed and the storage'capacity for the gas is reduced. This at the same time causes the valve to be lifted from its seat and a portion of carbid to be discharged into the water. This will cause the generation of gas, which will raise the carbid-holder and close the valve.

The carbid-holder is movably secured to the base by means of rods H, which are secured to the flange C and extend upwardly into tubes 11 within the carbid-holder. This permits the carbid-holder to rise and fall, while a burner J, which, as herein shown, lies within a reflector-cone K.

The construction shown 1n Fig. 5 is substantially that of Fig. 1 just described. The material difference is that the drying-chamher I is connected with the interior of the lamp by. means of a pipeJ The position or location of the burneris not anessential fea ture.- Inusingthe device asa bicyclelantern the burner would be located as shown.

In .using the device as a house -lam-p the burner-would probably be otherwise located. 1 As shown in Fig. 5, the pipe J, leading to they burner, is provided with a stop cook or valve J ;The5 conical flange O prevents the water con-tainedin the lower. portion of the lantern 'frombeing thrown upward, so as to moisten the carbid. :In use u-p'onbicycles the lantern isapt to be considerably shaken at times.

This will throw the water about somewhat.

Thewater being thrown against the sides of its containing-chamber willbe deflected lip-1 ward until it comes incontact with the con-- ical flange O. r This flange will then deflect thefwater downward and prevent any possibility of its getting into the upper part of the lantern l I containing chambers without necessitating a I seal would be very hard tomaintain.

claim as new and desire to secure by Letters.

The lanternas herein shown and described isvery simple andcheap in its construction,

while being atthe same time convenient and vnotlikely to getout of order.
